One of the first steps you take when you are estimating your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

A common way of making a decision about when it's possible to plant violets is to consult the USDA zone info for Zone 12a.

Planting Calendar for Violets

Frost tolerance for violets:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Violets do ok in a little bit of cold which tells us that you can plant them just a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant violets in Zone 12a is January. However, you really should wait until February if you don't want to take any chances.

The last month that you can plant violets and expect a good harvest is probably November. If you wait any later than that and your violets may not have a chance to really do well. If you are starting your violets indoors then you might be able to get away with starting them a little bit earlier.

Last Frost Date

In Zone 12a it never frosts. You should expect an average low temperature of 50°F in the coldest months of winter.

Since the USDA zone info for Zone 12a is not always accurate the actual date of last frost changes from year to year. Since it never frosts in Zone 12a you do not have to be ready to protect your violets in the event of a late frost.
